I Y

In order to; further guide the latch bolt .in its housing, the latch, bolt is provided with a guide pin. .33f slidably` mounted, in .a bearing 3A, on the plate I6 and which has its upper 'en df threaded as at to engage in the lower threaded end of 45 the: bore A2t and provide an. abutment fon the shank 29 of' the key 30 above'described.A The.v lowerwend of the guide pin `carries a head 36. seatingorie or more compressible `washers 31 to absorb shock and preventfthe -metallici :clickwhich Wouldfbe caused by the head 36 engaging the plate V when the latch bolt is driven tothe The frnnnwallofthe housing; has a rectangulara 55 slot 38 extending from its lower edge to a point adjacent its upper end and in which operates a projecting boss 39 that carries the bolt head 24. 'I'he head 24 is preferably formed integrally with the body portion of the latch bolt and includes a keeper engaging portion 48 having an upwardly inclined cam face 4| terminating in a rounded edge 42 over which-the keeperf 25 slides into engagement with a preferably inclined face 43 which provides wedge-like engagement of the keeper to take up play and securely retain the panel in closed position under action of the spring 3|.

The keeper 25 includes a plate portionu thatz is fixed to the inner face of the-panel 3 Vby fastening devices 45 extending through openings 46 therein and through aligning openings in theA cause lthe latch bolt toV be moved downwardly in its housing against tension ofthe spring 3|.l

When thelatch bolt ha's'been depressed to the point wherefthe tip 5| of the keeper rides overV therounded end 42 of the bolt head, the spring 3|"willbe automatically released to move the bolt'- Y into 'latching engagement with the keeper as shown in Fig. 3 tion.

Torelease the panel, the key 30 may be inserted'in-the bore of the boss`26 to depress the latch bolt against tension of vthe spring 3| until the rounded portion 42 clears the lower edge 5| of the keeper, after which thekeeper is free to be moved outwardly to release one'end ofthe panel as shown in Fig. '1.

to retain the panel in closed posi-r Where a latch is mounted on each end of the panel, as shown'y it is'diic'ultto release'both bolts at the same time.V I, therefore, provide each bolt with a detent 52 that is slidably mounted in-a'boreV 53 extending transversely across the v lowerportion of the bolt head as best illustrated in Fig. 6. VThe detent includes ahead portion T54 thatV is adapted to slidably'engage the face 55 of a lug 56 on the plate portion of the keeper so that when the panel is closed, the ldetent is retained in retractive position within the bore of the bolt head.

collar 58 slidable in an enlarged portion 59'of the bore 53. Sleeved over the shank 51V with one end engaging'against the collar 58 and its opposite end engaging a washer 60 is a vspring 6| tonormally urge` the detentinv contact with the face of `the-lugv The washer 6|)V isv retained in the open end o f the bore byfmeans of asplit ring 6 2 having itslouter periphery seated in `an an-j nular groove `63a`sfshown in Fig. 3.

It is thus apparent-that the spring. 6| retains the head of the detent in` yielding' engagement withthe face ofthe lug 56 butv when the bolt is depressed to 'release the keeper, vthe detent will ride oi the' bottom edge of the lug; whereupon 'the' springi6| will project the'detent under the shoulderY 64 that-is Vfrme'dby the lower edgeoff thelu'g. vThen when'pressure on the bolt is released, itwill be retainedinretracted position by means ofthe detent until the time that thefpanel f' -swun'fgf outwardly -to rer'noveY the .lug from "the Fig. 3;

The detent also includes a shank 51 having aA path of the detent. When this occurs, the bolt is released for return by its spring to its normal position.

Upon closing of the panel, the rounded nose portion of the keeper riding on the inclined face 5 4| will depress the bolt until the hook shaped edge of the keeper overrides the rounded portion ofthe bolt head, whereupon the spring 6| will return the boltinto latched engagement with the keeper. Due to the fact that the extent of depression of the bolt caused by the camming action of the keeper is less than required toe cause lthe detent to ride off the lug, the detent'l is retained in retractive position as shown in f l5 To relieve shearing stressesA on the fastening devices lll, the rear face of the bracket 8 is provided with spaced bosses 66 that are mounted in sockets formed in the inner faces of the end boards 4.

In order to assist in spacing the brackets so that the hook portion of the keeper is in proper relation with the bolt head, the side ,of the bracket adjacent the panel is provided with a laterally extending stop ange 81 adapted to abut against 25 the face of the panel at the time the edge 5| overrides the rounded end of the bolt head.

In the form of the invention shown in Fig. 8, the heads of the guide pins are provided'with exible cables whereby the latch bolts may be 30 selectively operated at aremote point, thereby eliminating the necessity of using the key 30.

In applying the latches constructed as described, recesses are madeon the inner faces of the end boards to accommodate the bosses 66, the recesses being so located that the ange 61 abuts squarely against the inner face of the panel 3. Holes arethen drilled for the fastening devices Ill which are extended therethrough and through the ears 9 of the bracket. The keepers 25 are then applied to the inner face of the panel in line with the cam face 4| of the bolt by drill- 5 ing holes through the panel in line with the openings 46, after which the fastening devices 45 are projected therethrough to'complete attachment of the keepers.

In this position, the faces 56 of the keepers cooperate with the wedge face 43 of the bolt heads to draw the panel tightly against the flange 61 to preventrattling vor looseness of the parts. Should wear occur between the faces 43 and 50, the spring 3| will maintain wedging engagement of the bolt heads with the hooked Vends of the keepers. Variation in relative position between the latch bolts and keepers may be compensated for by varying the thickness of the washers 3l that are applied to .thev guide pins 33.

To release the latches in the installation above describedthebolt for the latch.| is depressed by inserting the shank 29 of the key 38 into thc 60 bore 28 until the end thereof engages the end face of the guide pin 33.

Pressure is then applied .on the handle of the key to cause depression of the bolt 22 in the guide housing.Y This carries the latch bolt down- 65 Wardly away from the hook shaped end of the keeper; however, `downward movement of the latch bolt is continued until the detent 52 latches under the lower end of the lug 55. Then when the key isremoved, the detent will hold the ylatch bolt in disengaged relation with the keeper. The key may then be applied in the bore 28 of the latch 2 to cause depression of the bolt for that latch.l

The panelv is then freeto swing away from the stop flanges 61`car'rying5 weg-keepers therewith. 75

As soon as the shoulders 64 clear the detents, the springs 3| will raise the bolts carrying them to their original position. The spring 6I will have effected projection of the detents into the position shown in Fig. '7.

When the panel is moved to closed position, the rounded ends of the keepers will, upon engaging the inclined surfaces i of the bolt heads, cause downward movement thereof. the lugs 55 will have engaged the end of the detents 54 to cause their retraction within the bores 53; however, the keepers when finally latched with the bolts Will not have moved the bolts far enough to cause the ends of the detents to ride off the lower ends of the lugs.

If the latches are to be operated from a remote point, the heads of the guide pins 33 will be pro'- vided with flexible connections E through which unlatching movement of the bolts may be effected in substantially the same manner as with the key 30.

From the foregoing, it is apparent that I have provided a latch construction which may be readily operated and selectively retained in released condition so that a similar latch at the other end of a movable door or panel may be conveniently operated to release the panel.

It is also apparent that a single latch might be used on a door and operated remotely by a cable as indicated in Fig. 8.
